Authorization notice. Mailcheap is dual-use. Only use it on software, sites and systems you own or have explicit permission to test.

Credentials. An agent connected with an API key can act on your whole MailCheap account, so keep the key scoped to what you need and revoke it if it leaks.

Who it is forA creator or small publisher who wants a newsletter and website with no infrastructure to maintain.

The problemSetting up a newsletter stack means choosing a sender, a website, signup forms and deliverability settings, which takes time before the first issue goes out.

The outcomeA working newsletter with a signup form, a website for its issues, and a first issue reviewed and ready to send.

What you need first

  • A MailCheap Cloud account at mailcheap.ai, or a server with Node.js 22+ and a MongoDB database for self-hosting
  • For self-hosting: an Amazon SES or PostShiba account, plus Upstash QStash for background sending
  • A list of contacts with consent to email them, or an export CSV from beehiiv, Substack, Mailchimp or another supported tool
  • An AI agent or API key if you want an agent to write or send issues

Steps

  1. Sign up at https://mailcheap.ai. Plans start at $19 a month for 20,000 emails.
  2. Create a newsletter. Without your own domain, it sends from a shared address on the Mailcheap.ai subdomain, and its website sits on a free subdomain of Mailcheap.ai.
  3. Write an issue in the editor, or send Markdown or complete HTML through the API.
  4. Open the review step and fix what it flags: subject, preview text, unsubscribe link, Gmail's 100 KB clip, postal address and sender.
  5. Send the issue now, schedule it, or send to your most engaged readers first and the rest later.

Prompt for your agent

Using the marclou/mailcheap repository's MCP server with an API key for <your MailCheap Cloud account>, create a newsletter named <newsletter name> and draft a first issue about <topic>. Report the review checklist results and do not send anything. Verify that the draft appears in the dashboard before you finish.

Caveat. MailCheap Cloud is the hosted version of this same code, and only active subscribers count toward a plan, so dormant contacts do not raise your bill.
